  At the lower end of the dewatering shaft 19 of the centrifugal dewatering unit 5, a scraping blade 30 for carrying grains (rice grains) into the tempering / drying unit 6 is pivotally attached, and the rice grains are diffused into the tempering / drying unit 6. It can be carried in. The centrifugal dewatering unit 5 and the tempering / drying unit 6 are connected to each other by a flow basin 31 like a circular arc with a gentle vertical cross section, and coupled with the raking blade 30, the dehydrated rice grains are removed. It can be carried into the tempering / drying unit 6 while being diffused.

  The tempering / drying unit 6 includes a vibrator frame 35 having first, second, and third screens 32, 33, 34 for exposing (exposing) rice grains to hot air while rolling rice grains, and the vibration frame. 35, an elastic member 36 for supporting the screen by suspending, a vibration motor 37 for finely vibrating the entire vibrator frame 35, a hot air supply fan 38 with a heater built therein, and the wind passing through the screens 32, 33, 34. And a refined duct 40 for discharging the conditioned and dried rice grains to the outside of the machine.

  A grain input port 41 is provided on the start side 7 a of the finer tube 3 of the finer part 3. Then, a grain input hopper 42 slightly shifted to the outer peripheral side is arranged so that the grain can be input from the tangential direction of the outer peripheral edge 7g of the starter side 7a (FIGS. 1, 4A). ), FIG. 4 (B)). The grain input hopper 42 is provided with an inclined chute 43 having a width of about 120 mm and a length of about 150 mm, for example, and a water supply nozzle 44 is fixed to the lower end of the inclined chute 43. Thereby, when throwing a grain into the grain inlet 41 from the inclination chute 43, it can be thrown in in the state which aligned the grain from the tangential direction of the outer periphery 7g. In addition, since water is added from the water supply nozzle 44 while the grain falls from the lower end of the inclined chute 43 to the tub tube 7, the pressure of water due to the water is weakened by the momentum of the grain flow to prevent splashing. Can do. Reference numeral 45 is a water supply port at the tip of the water supply nozzle 44, and the water supply port 45 is a wide opening (see FIG. 4B) across the width direction of the inclined chute 43.

Reference numeral 46 denotes a water supply pipe, and reference numeral 47 denotes a joint that connects the water supply pipe 46 and the water supply nozzle 44. Water is supplied to the water supply nozzle 44 through the water supply pipe 46 and the joint 47 by a pump (not shown). be able to.

  Next, the operation of the non-washed grain manufacturing apparatus having the above configuration will be described. The polished rice, which is the raw material supplied from the raw material supply chute 50, is quantitatively supplied to the rice grain input hopper 42 by the rotary valve 51 which is the grain supply device 4. Then, the rice grains reach the grain input hopper 42 from the passage 52. In the grain input hopper 42, the slant chute 43 provided in the hopper is input into the milling cylinder 7 in an aligned state from the tangential direction of the outer peripheral edge 7g. The At this time, water is added by a water supply nozzle 44 fixed to the lower end portion of the inclined chute 43, for example, 10 to 20% by weight with respect to polished rice.

  And since the addition of water from the water supply nozzle 44 is performed in the middle of the rice grain falling from the lower end of the inclined chute 43 to the milling tube 7, the pressure at the time of water addition by water is weakened by the momentum of the rice grain flow, Splashing can be prevented. Further, since the water supply port 45 at the tip of the water supply nozzle 44 is a wide opening over the entire width of the inclined chute 43 (see FIG. 4B), all of the water flowing down the inclined chute 43 is used. Water can be added evenly to the rice grains without any unevenness, which can contribute to quality improvement.

  Next, the rice grains are fed to the milling cylinder 7 side by the cerealing screw 9 in the milling cylinder starting end side 7 a, and the milling cylinder 7 is stirred and milled by a plurality of stirring blades 10. In milled rice, the milled portion produced by milling is diffused into the water, and milling is performed by particle friction in the water. At this time, the accuracy of the wrinkle advances by 0.5 to 2.0% with respect to the rice grains, so that the Aleurone layer on the surface of the rice grains peels off. During such agitation and milling, the flow of rice grains from the milling cylinder 7 is regulated by the regulating member 12 attached to the milling shaft 8. At this time, the dimension of the gap between the regulating member 12 and the fine milling cylinder 7 is preferably set in a range of 3 to 15 mm, more preferably in a range of 5 to 13 mm, in which rice grains can flow out.

  FIG. 5 is an enlarged view when broken along the line AA in FIG. The regulating member 12 pivotally attached to the tip of the milling shaft 8 has its outer diameter close to the inner diameter of the milling tube 7 to narrow the gap, so that the flow of polished rice from the milling tube 7 is regulated. With reference to FIG. 5, an example of the dimension of the regulating member 12 and the fine barrel 7 is shown. The restricting member 12 has a disc shape and has an outer diameter of 140 mm. The inner diameter of the narrowest portion of the substantially hexagonal fine tube 7 is 150 mm, and the inner diameter of the widest portion of the fine tube 7 is 166 mm. The gap through which the rice grains can flow was 13 mm at the maximum and 5 mm at the minimum. By forming in such a gap size, the rice grains can be supplied to the centrifugal dewatering unit 5 while restricting the outflow from the milling cylinder 7.

  As described above, as a method of supplying rice grains to the next step (for example, centrifugal dehydration unit 5) while restricting the outflow from the milling cylinder 7, conventionally, the method described in paragraph 0006 of Japanese Patent Laid-Open No. 5-68896 and FIG. There was a method in which a resistance lid was pressed against the outlet. However, in such a pressure regulating mechanism that presses the resistance lid against the discharge port, it has to be connected to the next process via a receiving hopper as a separate part, and there is a problem that the size of the airframe is increased.

  On the other hand, when the restricting member 12 is pivotally attached to the tip of the fine shaft 8 as in this embodiment and the gap with the fine tube 7 is narrowed, the fine tube 7 can be directly connected to the dewatering tube 18. This has the advantage of reducing the size of the aircraft. And since underwater milling is performed while regulating the outflow of polished rice from the milled rice 7 by the regulating member 12, it is possible to provide a washing-free rice production apparatus that is less likely to cause residual deposits in the milled rice mill 7 and excellent in hygiene. Is possible.

  Next, the operation will be described. Next, when the rice grains are supplied to the dewatering cylinder 18 of the centrifugal dewatering unit 5, the rice grains and water are transferred in the vertical direction by the rotation of the dewatering screw 20 (for example, 2000 rpm) in the centrifugal dewatering unit 5. As the water and water are transported, they are subjected to the action of centrifugal force due to the rotation of the dehydrating cylinder 18 (for example, 1700 rpm), and are separated into rice grains and water containing soot and aleurone in the porous wall portion 17 of the dehydrating cylinder 18. The The separated water is discharged out of the machine through the drainage cover 21 and the drainage basin 22 and is subjected to drainage treatment at a drainage treatment facility (not shown). Is scraped out from the dehydrating cylinder 18 through the scraping blade 30 and transferred to the tempering / drying unit 6 through the downflow basin 31.

  In the tempering / drying unit 6, when rice grains are supplied to the first screen 32 in the vibrator frame 35, the rice grains are sequentially transferred to the first screen 32, the second screen 33 and the third screen 34 by the vibration motor 37. It is transferred while being moved. Also, hot air from the hot air supply fan 38 is supplied from below the first screen 32, the second screen 33, and the third screen 34, and is exposed (exposed) to the hot air while rolling the rice grains. Tempering and drying. Then, from the refined duct 40, for example, unwashed rice having a water content of about 15% is discharged.

  Washing-free rice is produced as described above. In this embodiment, the milling unit 3 is rotatably supported in the milling cylinder 7 and the cerealing screw that is pivotally attached to the milling shaft 8. 9, a stirring trochanter 11 to which a plurality of stirring blades 10 are fixed and attached to the fine shaft 8 is attached to the tip of the fine shaft 8 so that there is a gap between the inner diameter of the fine tube 7 And a regulating member 12 that narrows and regulates the flow of rice grains from the milling cylinder 7, so that underwater milling is performed while regulating the flow of rice grains from the milling cylinder 7 by the regulating member 12. It becomes possible to provide an unwashed grain manufacturing apparatus excellent in hygiene, since the inside of the cylinder 7 is always full and hardly causes residual deposits. In addition, since the squeezing unit 3 and the centrifugal dewatering unit 5 are received and can be continuously connected directly without using a hopper, the size of the aircraft can be reduced.

  Further, a grain input hopper 42 for supplying rice grains to a grain input port 41 opened in the fine milling cylinder is disposed on the start side 7 a of the fine grain cylinder 3, and the grain input hopper 42 includes a grain input hopper 42. Since the inclined chute 43 is provided and the wide water supply port 45 having a width dimension substantially equal to the width direction dimension of the inclined chute 43 is opened at the lower end of the inclined chute 43, the rice grains are crushed from the lower end of the inclined chute 43 Since water is added from the water supply nozzle 44 in the middle of dropping into the water 7, the pressure of water during the addition is weakened by the momentum of the rice grains flowing, and there is an advantage that splashing can be prevented.

  The present invention can be applied to a washing-cereal manufacturing apparatus.
